Some 200,000 mail carriers have reached a tentative contract deal with the U.S. Postal Service that includes backdated pay raises and a promise to provide workers with air-conditioned trucks.

The new agreement, which still needs to be ratified by union members, runs through November 2026. Letter carriers have been working without a new contract since their old one expired in May 2023. Since then they have continued working under the terms of the old contract.

Both the union and the Postal Service welcomed the agreement, which was announced Friday.

“Both sides didn’t get everything they wanted. But by bargaining in good faith, we ended with an agreement that meets our goals and rewards our members,” Brian Renfroe, the president of the National Association of Letter Carriers, told The Associated Press. “To make that happen, the Postal Service had to recognize the contributions of members to the Postal Service and the American people.”

Among other improvements, the deal increases the top pay and reduces the amount of time it takes new workers to reach that level, Renfroe said. He credited Postmaster General Louis DeJoy and his deputy for bargaining in good faith throughout the arduous process.

The Postal Service said the agreement supported its 10-year “Delivering for America” mission to modernize operations and adapt to changing customer needs.

“This is a fair and responsible agreement that serves the best interest of our employees, our customers and the future of the Postal Service,” said Doug Tulino, the deputy postmaster general and chief human resources officer.

As part of the agreement, all city carriers will get three annual pay increases of 1.3% each by 2025, some of which will be paid retroactively from Nov. 2023. Workers will also receive retroactive and future cost-of-living adjustments.

There is also a commitment from the Postal Service to “make every effort” to provide mail trucks with air-conditioning.

In the summer the Postal Service began rolling out its new electric delivery vehicles, which come equipped with air-conditioning. While the trucks won’t win any beauty contests, they did get rave reviews from letter carriers accustomed to older vehicles that lack modern safety features and are prone to breaking down – and even catching fire.

Within a few years, the new fleet will have expanded to 60,000, most of them electric models, serving as the Postal Service’s primary delivery truck from Maine to Hawaii.

Under the tentative contract agreement, the Postal Service must discuss with the union any plans to buy new mail trucks that don’t have air-conditioning.

This is the second contract negotiated since DeJoy was appointed in 2020. It is expected to take several weeks for union members to ratify it.

Rural mail carriers are not covered by the contract because they are represented by a different union.
